The World Museum of Mining rests on land once occupied by the Orphan Girl Mine, and is therefore heir to that operation's authentic 100-foot steel headframe, or "gallows frame". Silver and zinc were the main ores extracted from the Orphan Girl, although the site overlooks the area of the 1864 gold strike. In fact, over 7,500,000 ounces of silver were produced from the "Girl" during her history, which extended from 1875 until 1956 — but a measure of the richness of Butte is the fact that this amounted to only 1% of all the silver ever produced in the whole district.
